Take a tour of Cube Houses of Rotterdam in Rotterdam, Netherlands – part of the World’s Greatest Attractions series by GeoBeats. Rotterdam is a city known for its innovate and modernistic art. This becomes expressed in odd places, such as the architecture of the bizarre Cube Houses. Piet Blom was the architect for these science fiction-esque dwelling places. These boxy homes come in a veritable forest of many buildings, all attached to each other. This is no public art display or tourist attraction; people do live in the houses. That said, one of the Cube Houses has been turned into an "show cube" for visitors' curiosity.
